Recent technological improvements have made possible the development of lightweight GPS-tagging devices suitable to track medium-to-small sized animals. However, current inferences concerning GPS performance are based on heavier designs, suitable only for large mammals. Lightweight GPS-units are deployed close to the ground, on species selecting micro-topographical features and with different …
There was marked acceleration in the loss of glacial mass in the Everest area between 2002 and 2005 compared to the earlier years, a new finding shared by scientists on Sunday revealed. The findings in the new report on ‘The Status of Glaciers in the Hindu Kush-Himalayan (HKH) Region’ shared …
Deforestation and forest degradation are down moderately from August through October 2011 relative to the same period a year ago, reports a satellite-based assessment released today by Imazon, a Brazilian group. Imazon's near-real time system, which tracks change in forest plots 25 hectares (62 acres) or larger, found that 512 …
Urbanization has been haphazard in Guwahati which has increased the chances of damage in the event of an earthquake and remote sensing technology will help reduce risks posed by quakes GUWAHATI1: Remote sensing technology will now be used to reduce seismic risks in urban planning in Assam. The government has …
A study was carried out in village Mohamadabad, Nalgonda district, Andhra Pradesh to demonstrate the potential of high-resolution remote sensing data in generating soil resource database at village level that would facilitate natural resource developmental planning. For this study, detail soil resource database was generated by interpreting IRS Resourcesat-1 LISS-IV …
The Dibru river basin of Assam is investigated to examine the influence of active structure by applying an integrated study on geomorphology, morphotectonics, subsurface structure, Digital Elevation Model (DEM) using topographic map, IRS 1D LISS III, IRS P6 LISS III, SRTM, seismic and subsurface data.
Landslide is a common natural hazard that usually occurs in mountainous areas. Rapid urban development and high traffic intensity movements have been hampered to a great extent by phenomenon of landslides. In the present study, Maco Landslide Hazard Zonation was carried out in the Bodi-Bodimettu ghats section, Western Ghats, Theni …
This paper presents the results of a preliminary study to assess the potential of the visible, NIR and SWIR energy of the EMR in differentiating iron ores of different grades in a rapid manner using hyperspectral radiometry. Using different iron ore samples from Noamundi and Joda mines, Jharkhand and Orissa, …
Trophic State Index (TSI) of Nainital Lake has been determined using secchi disk transparency as well as using Landsat 7 ETM bands. Various interpolation techniques have been tested and the best one has been applied to prepare the water quality images of Nainital Lake.
Sikkim is a small, mountainous, Indian state (7,096 km2) located in the eastern Himalayan region. Though a global biodiversity hotspot, it has been relatively less studied. A detailed forest type, density and change dynamics study was undertaken, using SATELLITE remote sensing data and intensive field verification.
Ground water is an excellent solvent, which dissolves chemicals ions as it moves through rocks and subsurface soil. This leads to more mineralization in groundwater than surface water. The objective of the present study is to examine the groundwater quality of the Paravanar River Sub-basin, Cuddalore district, Tamil Nadu, India. …
In this present study, the soil erosion assessment and conservation measures in hill ecosystem is carried out in the Kalrayan hills, Part of Eastern ghats, Tamil Nadu using Remote Sensing and GIS techniques. The geocoded digital data of IRS P6 LISS – III (P101-R65 of 2001) and Survey of India …
The amount and intensity of runoff at catchment scale are largely determined by the presence of impervious land cover types, which are predominant in an urbanized area. This paper examines the impact of different methods for estimating impervious surface cover on the prediction of peak discharges as determined by a …
Sikkim is a small, mountainous, Indian state (7,096 km2) located in the eastern Himalayan region. Though a global biodiversity hotspot, it has been relatively less studied. A detailed forest type, density and change dynamics study was undertaken, using satellite remote sensing data and intensive field verification. The landscape was found …
Mapping of extent of urban sprawl and by monitoring the temporal changes, the impact of changing land use on land, ecology and environment system can be assessed.
Development of representative conceptual groundwater flow model is an important step before translating it into a numerical model. In this paper, a methodology for development of conceptual groundwater flow model has been presented in which spatially distributed values for groundwater recharge has been utilized instead of lump sum average values …
Sundarban is perhaps the only forest in India where no cattle or other easy prey is available for old and injured tigers, forcing them to swim across the water channels to hunt for easy prey i.e. the cattle in the villages.
Sal (Shorea robusta Roth) is one of the most important timber-yielding plants in India, known for its heavy, hard and tough wood. Sal is an important source of hardwood timber in India, with hard, coarse-grained wood.
Climate change mitigation projects in developing countries have the potential for significant negative impacts on land users. In particular, land users with socially legitimate but informal tenure that is not recorded using a statutory process are at risk of exploitation from the powerful elite. A detailed understanding of de facto …
